Ergotron HX Dual Monitor Desk Arm Black
PRODUCT DESCRIPTION
Ergotron HX Dual Monitor Desk Arm Black (45-476-224) - 10 Years Local Warranty
Two Screens up to 32 Inches From a Single Desk Fixing
The Ergotron HX Dual Monitor Desk Arm (45-476-224) carries two displays up to 32″ each — 5–17.5 lbs (2.3–8 kg) per screen, 10–35 lbs (4.6–15.8 kg) in total — on one heavy-duty arm and one desk clamp or grommet. For Singapore finance desks, engineering benches, service desks and NOC positions where dual 27–32″ screens are the standard build, it replaces two factory stands with a single clean installation.
Constant Force Lift Moves Both Screens Together
Ergotron's patented Constant Force™ technology gives 11.5″ (29.2 cm) of one-touch vertical adjustment across the whole dual assembly, so both displays rise and fall together to the user's eye line without tools, knobs or gas struts. On shared and hot-desked positions that matters — the next user resets the workstation in seconds.
24.5 Inches of Reach and a Hinge Bow That Angles Both Displays
The arm extends up to 24.5″ (60 cm), and the hinge bow lets the two screens be angled inward into a shallow arc for a single user or swung flat to share with a colleague. A carry handle is included for repositioning the assembly during fit-out.
Reclaims the Desk Two Monitor Stands Would Occupy
Removing two factory stands and floating both panels frees the deepest, most useful part of the worksurface — a real gain on the 600–700 mm bench desks typical of Singapore offices. Integrated cable routing keeps four or more leads off the desk, and 70° of backward tilt with 5° forward handles overhead glare from ceiling lighting.

Compatibility & Fit
The HX Dual Monitor Desk Arm carries two screens side by side on a hinge bow from a single desk fixing. Note that a dual arm redistributes the HX platform's strength across two positions, so the per-screen limits are lower than the single-screen HX — check both the weight and the size figures below.
| VESA Pattern | MIS-D 100/75 C — 100 x 100 mm and 75 x 75 mm |
| Screen Size | Up to 32″ per display |
| Weight Per Screen | 5–17.5 lbs (2.3–8 kg), measured without the factory stand |
| Total Load | 10–35 lbs (4.6–15.8 kg) |
| Number of Screens | Two, side by side |
| Desk Clamp | Fits desk edges 0.4″–2.4″ (1–6 cm) thick |
| Grommet Mount | Included for a hole through the worksurface |
| Wall Mounting | Not applicable — see the HX Wall Dual Monitor Arm (45-479) |
Ultrawide and curved screens: two ultrawides will normally exceed the 32″ per-display limit. Where a single very large screen is genuinely the requirement, the single-screen HX Desk Monitor Arm (49″, 42 lbs) or the HX Desk Monitor Arm with HD Pivot for 1000R panels is the right product. Two gently curved 27–32″ panels inside the weight limit are well handled by this arm.
Three screens: the HX Triple Monitor Bow Kit (98-009-216) extends an HX configuration to a third display where the desk and the load budget allow.

Frequently Asked Questions — Ergotron HX Dual Monitor Desk Arm
What is the difference between the HX Dual finishes?
Only the colour. 45-476-026 is polished aluminium, 45-476-216 is white and 45-476-224 is matte black. Capacity, lift, reach, VESA support and box contents are identical across all three.
What monitor size and weight does the HX Dual support?
Two displays up to 32″ each, weighing 5–17.5 lbs (2.3–8 kg) per screen and 10–35 lbs (4.6–15.8 kg) in total, measured without the factory stands.
Why is the per-screen capacity lower than the single-screen HX?
Because a dual arm distributes the platform's strength across two mounting positions and a hinge bow. The single-screen HX (45-475) concentrates all of it on one display, which is why it reaches 42 lbs and 49″ while the dual is rated to 17.5 lbs and 32″ per screen.
How does it mount, and how thick can my desk be?
A desk clamp and a grommet mount are both supplied. The clamp fits desk edges 0.4″–2.4″ (1–6 cm) thick; the grommet mount drops through a hole in the worksurface. One desk fixing carries both screens.
Do I need a VESA adapter?
Not for standard displays — VESA MIS-D 100 x 100 mm and 75 x 75 mm are supported natively. Screens with a larger or proprietary pattern need the display manufacturer's VESA adapter plate.
Can I add a third monitor later?
Yes — the HX Triple Monitor Bow Kit (98-009-216) extends an HX configuration to three screens, subject to the total load budget and available desk width.
How does this compare with the Ergotron LX Dual arms?
The LX Dual Desk Mount Side-by-Side Arm (45-245-026) and LX Dual Stacking Arm (45-248-026) are the lighter-duty options for smaller office monitors. The HX Dual has a heavier frame, 11.5″ of Constant Force lift and up to 24.5″ (60 cm) of reach, and suits larger 27–32″ panels on deeper desks.
Does the HX Dual Monitor Desk Arm come with a Singapore warranty?
Yes. Every Ergotron HX Dual Monitor Desk Arm sold by SourceIT comes with local Singapore warranty and a GST invoice; Ergotron backs the HX Dual Monitor Desk Arm with a 10-year manufacturer warranty.
